I am newbie using thinger.
I already successfully installed MongoDB and Thinger on my Ubuntu 16.04 server.
I tried to follow the instruction on the server deployment.
I also configured the config.json file according to my server IP address.

Can you please post the log generated by the server? The config.json file would be useful also if you made any change.

You should not touch the server IP address in the config.json file, as it will change the network interface where it listen to receive new connections (unless you have a server with different interfaces and want to only provide thinner.io service from one of them). So, if you just want your server to be reachable from any interface, just keep it 0.0.0.0.
